Human clinical research has become a huge economic enterprise (Morin et al. 2002; Noah 2002). Because the human subject at the center can be so easily marginalized, many commentators recommend spec...

Recent debates over adults' theory of mind use have been fueled by surprising failures of perspective-taking in communication, suggesting that perspective-taking may be relatively effortful. Yet adults routinely engage in effortful processes when needed. How, then, should speakers and listeners allocate their resources to achieve successful communication? We begin with the observation that the shared goal of communication induces a natural division of labor: The resources one agent chooses to allocate toward perspective-taking should depend on their expectations about the other's (...) allocation. We formalize this idea in a resource-rational model augmenting recent probabilistic weighting accounts with a mechanism for (costly) control over the degree of perspective-taking. In a series of simulations, we first derive an intermediate degree of perspective weighting as an optimal trade-off between expected costs and benefits of perspective-taking. We then present two behavioral experiments testing novel predictions of our model. In Experiment 1, we manipulated the presence or absence of occlusions in a director–matcher task. We found that speakers spontaneously modulated the informativeness of their descriptions to account for “known unknowns” in their partner's private view, reflecting a higher degree of speaker perspective-taking than previously acknowledged. In Experiment 2, we then compared the scripted utterances used by confederates in prior work with those produced in interactions with unscripted directors. We found that confederates were systematically less informative than listeners would initially expect given the presence of occlusions, but listeners used violations to adaptively make fewer errors over time. Taken together, our work suggests that people are not simply “mindblind”; they use contextually appropriate expectations to navigate the division of labor with their partner. We discuss how a resource-rational framework may provide a more deeply explanatory foundation for understanding flexible perspective-taking under processing constraints. (shrink)

The language we use over the course of conversation changes as we establish common ground and learn what our partner finds meaningful. Here we draw upon recent advances in natural language processing to provide a finer‐grained characterization of the dynamics of this learning process. We release an open corpus (>15,000 utterances) of extended dyadic interactions in a classic repeated reference game task where pairs of participants had to coordinate on how to refer to initially difficult‐to‐describe tangram stimuli. We find that (...) different pairs discover a wide variety of idiosyncratic but efficient and stable solutions to the problem of reference. Furthermore, these conventions are shaped by the communicative context: words that are more discriminative in the initial context (i.e., that are used for one target more than others) are more likely to persist through the final repetition. Finally, we find systematic structure in how a speaker's referring expressions become more efficient over time: Syntactic units drop out in clusters following positive feedback from the listener, eventually leaving short labels containing open‐class parts of speech. These findings provide a higher resolution look at the quantitative dynamics of ad hoc convention formation and support further development of computational models of learning in communication.

Scholars of classical philosophy have long disputed whether Aristotle was a dialectical thinker. Most agree that Aristotle contrasts dialectical reasoning with demonstrative reasoning, where the former reasons from generally accepted opinions and the latter reasons from the true and primary. Starting with a grasp on truth, demonstration never relinquishes it. Starting with opinion, how could dialectical reasoning ever reach truth, much less the truth about first principles? Is dialectic then an exercise that reiterates the prejudices of one's times and at (...) best allows one to persuade others by appealing to these prejudices, or is it the royal road to first principles and philosophical wisdom? In From Puzzles to Principles? May Sim gathers experts to argue both these positions and offer a variety of interpretive possibilities. The contributors' thoughtful reflections on the nature and limits of dialectic should play a crucial role in Aristotelian scholarship. (shrink)

This is an exploration of modernism and postmodernism in regard to knowledge: methods of inquiry, operations of the mind, the role of values, conceptions of self, and the problematic of reason.

Two groups of plant viruses have DNA in their genomes. One group, the caulimoviruses, are non‐integrating retroviruses that package dsDNA in virions. The other group, the geminiviruses, package small circular ssDNA and include the only DNA viruses known with bipartite genomes. The regulation of transcription of these viruses is not well characterized, but recent work is beginning to yield interesting results. Regulatory sequences from these viruses function in cells of species that are not hosts of the virus and are finding (...) use in constitutive expression of chimeric genes in transformed plants. Development of vectors based on plant viruses requires further characterization at the molecular level of viral life cycles. (shrink)

Let me begin by saying that this is an admirable collection, one that lives up to its title. William James, perhaps uniquely, is a philosopher who invites the companionship of others. One by one, the authors of these essays have accepted his invitation, each entering into a conversation with him. Ruth Anna Putnam has brought together a varied and interesting collection of essays; and I strongly recommend it both to specialists and to readers who may not yet be familiar with (...) his work.

We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

This paper is a study of higher-order contingentism – the view, roughly, that it is contingent what properties and propositions there are. We explore the motivations for this view and various ways in which it might be developed, synthesizing and expanding on work by Kit Fine, Robert Stalnaker, and Timothy Williamson. Special attention is paid to the question of whether the view makes sense by its own lights, or whether articulating the view requires drawing distinctions among possibilities that, according (...) to the view itself, do not exist to be drawn. The paper begins with a non-technical exposition of the main ideas and technical results, which can be read on its own. This exposition is followed by a formal investigation of higher-order contingentism, in which the tools of variable-domain intensional model theory are used to articulate various versions of the view, understood as theories formulated in a higher-order modal language. Our overall assessment is mixed: higher-order contingentism can be fleshed out into an elegant systematic theory, but perhaps only at the cost of abandoning some of its original motivations.

Advanced Cell Technology's Ethics Advisory Board has been called window dressing for a corporate marketing plan. But the scientists and managers have paid attention, and the lawyers have gone along.

This article explores the connection between two theses: the principle of conditional excluded middle for the counterfactual conditional, and the claim that it is a contingent matter which (coarse grained) propositions there are. Both theses enjoy wide support, and have been defended at length by Robert Stalnaker. We will argue that, given plausible background assumptions, these two principles are incompatible, provided that conditional excluded middle is understood in a certain modalized way. We then show that some (although not all) (...) arguments for conditional excluded middle can in fact be extended to motivate this modalized version of the principle. (shrink)

The Pragmatism Reader is the essential anthology of this important philosophical movement. Each selection featured here is a key writing by a leading pragmatist thinker, and represents a distinctively pragmatist approach to a core philosophical problem. The collection includes work by pragmatism's founders, Charles Peirce, William James, and John Dewey, as well as seminal writings by mid-twentieth-century pragmatists such as Sidney Hook, C. I. Lewis, Nelson Goodman, Rudolf Carnap, Wilfrid Sellars, and W.V.O. Quine. This reader also includes the most (...) important work in contemporary pragmatism by philosophers like Susan Haack, Cornel West, Hilary Putnam, Richard Rorty, Cheryl Misak, and Robert Brandom. Each selection is a stand-alone piece--not an excerpt or book chapter--and each is presented fully unabridged. The Pragmatism Reader challenges the notion that pragmatism fell into a midcentury decline and was dormant until the advent of "neopragmatism" in the 1980s. This comprehensive anthology reveals a rich and highly influential tradition running unbroken through twentieth-century philosophy and continuing today. It shows how American pragmatist philosophers have contributed to leading philosophical debates about truth, meaning, knowledge, experience, belief, existence, justification, and freedom. Covers pragmatist philosophy from its origins to today Features key writings by the leading pragmatist thinkers Demonstrates the continuity and enduring influence of pragmatism Challenges prevailing notions about pragmatism Includes only stand-alone pieces, completely unabridged Reflects the full range of pragmatist themes, arguments, concerns, and commitments.

The extensions of Goodman’s ‘grue’ predicate and Kripke’s ‘quus’ are constructed from the extensions of more familiar terms via a reinterpretation that permutes assignments of reference. Since this manoeuvre is at the heart of Putnam’s model-theoretic and permutation arguments against metaphysical realism (‘Putnam’s Paradox’), both Goodman’s New Riddle of Induction and the paradox about meaning that Kripke attributes to Wittgenstein are instances of Putnam’s. Evidence cannot selectively confirm the green-hypothesis and disconfirm the grue-hypothesis, because the theory of which (...) the green-hypothesis is a part has an unintended model in which the grue-hypothesis is equally confirmed; and there are no meaning-facts that determine reference, because the objects referred to by the referring terms of any language or set of intentional mental states are permutable in a way that is consistent with the truth-values of all other sentences in that language or beliefs in that set. The upshot is that the three paradoxes need to be solved in a unified way. (shrink)

The Kripke/Wittgenstein paradox and Goodman’s riddle of induction can be construed as problems of multiple redescription, where the relevant sceptical challenge is to provide factual grounds justifying the description we favour. A choice of description or predicate, in turn, is tantamount to the choice of a curve over a set of data, a choice apparently governed by implicitly operating constraints on the relevant space of possibilities. Armed with this analysis of the two paradoxes, several realist solutions of Kripke’s paradox (...) are examined that appeal to dispositions or other non-occurrent properties. It is found that all neglect crucial epistemological issues: the entities typically appealed to are not observational and must be inferred on the basis of observed entities or events; yet, the relevant sceptical challenge concerns precisely the factual basis on which this inference is made and the constraints operating on it. All disposition ascriptions, the thesis goes on to argue, contain elements of idealization. To ward off the danger of vacuity resulting from the fact that any disposition ascription is true under just the right ideal conditions, dispositional theories need to specify limits on legitimate forms of idealization. This is best done by construing disposition ascriptions as forms of (implicit) curve-fitting, I argue, where the “data” is not necessarily numeric, and the “curve” fitted not necessarily graphic. This brings us full circle: Goodman’s and Kripke’s problems are problems concerning curve-fitting, and the solutions for it appeal to entities the postulation of which is the result of curve-fitting. The way to break the circle must come from a methodology governing the idealizations, or inferences to the best idealization, that are a part of curve-fitting. The thesis closes with an argument for why natural science cannot be expected to be of much help in this domain, given the ubiquity of idealization. (shrink)

Open peer commentary on the article “A Defence of Starmaking Constructivism: The Problem of Stuff” by Bin Liu. Abstract: I present alternative responses to those Liu offers to two challenges to Nelson Goodman’s constructivist thesis: A. it is not possible for everything to be constructed and B. the thesis cannot account for the existence of things prior to their being constructed.

Belief revision theory concerns methods for reformulating an agent's epistemic state when the agent's beliefs are refuted by new information. The usual guiding principle in the design of such methods is to preserve as much of the agent's epistemic state as possible when the state is revised. Learning theoretic research focuses, instead, on a learning method's reliability or ability to converge to true, informative beliefs over a wide range of possible environments. This paper bridges the two perspectives by assessing the (...) reliability of several proposed belief revision operators. Stringent conceptions of “minimal change” are shown to occasion a limitation called inductive amnesia: they can predict the future only if they cannot remember the past. Avoidance of inductive amnesia can therefore function as a plausible and hitherto unrecognized constraint on the design of belief revision operators. (shrink)

In Howard Kahane's current reply to my previous discussion of Goodman's elimination rules, he suggests both that the notion of conflict required by the first elimination rule cannot be made clear, and that both proposed revisions of the second elimination rule are too strong [4]. These seem to me to be the points which require settlement, and I would like to discuss them in this paper.

This is a fine introduction to the study of pragmatism. It is well written, thoroughly researched, and clearly focused in presenting the history and implications of the core positions of classical and contemporary pragmatists. It is targeted basically for the general college and university student in American and Western Philosophy, the History of Philosophy, and American Studies. Without too much of a stretch, it seems equally suitable for the general reader familiar with some philosophy outside the academic and scholarly community. (...) Also, the author introduces from time to time generally reliable criticisms of core points various authors make. While the selections of pragmatic authors covered are representative of some classical and contemporary pragmatists, some prominent pragmatists did not make the final cut, including Royce, Mead, Lewis, Goodman, Carnap, Reichenbach, Rescher, and van Fraassen. But it is still a good introduction to what all pragmatists have in common, although the .. (shrink)

These essays by Robert Schwartz on topics in the theory of vision are written from a pragmatic perspective. The issues and arguments will interest both philosophers and psychologists, covering new ground and bridging gaps between these disciplines. Schwartz begins historically, with discussions of problems raised and solutions offered in Bishop Berkeley's writings on vision, presenting Berkeley's views on spatial perception and the qualitative aspects of sensory experience in the context of recent theoretical and empirical work in vision theory. Schwartz (...) then turns to debates in both the philosophical and psychological literature over the view that perception is inferential and thus "indirect." Critically surveying competing characterizations of the idea of "inferential processes" he argues the need either to reframe radically the question or drop the issue. Next, Schwartz discusses pictorial representation and research on picture perception. Drawing on the work of Nelson Goodman, Schwartz explains and defends the advantages of a symbolic approach to both topics. Finally, he examines the quagmires that often develop when metaphysical concerns about the "real" and our ability to perceive it infect discussions and claims in the theory of vision. After analyzing issues arising in current psychological research on "object" perception, Schwartz turns to debates over the supposed essential nature of colors. An appreciation of the empirical and theoretical work on color perception suggests that there is no single or privileged analysis of the notion of "real colors." Schwartz circles back in the end to what he calls "that old chestnut of the philosophy of perception"--controversies over "the objects of perception"--and takes an Austinian look at the topic.

Israel 2004 claims that numerous philosophers have misinterpreted Goodman’s original ‘New Riddle of Induction’, and weakened it in the process, because they do not define ‘grue’ as referring to past observations. Both claims are false: Goodman clearly took the riddle to concern the maximally general problem of “projecting” any type of characteristic from a given realm of objects into another, and since this problem subsumes Israel’s, Goodman formulated a stronger philosophical challenge than the latter surmises.

This paper summarises the main claims I have made in a series of publications on depiction. Having described six features of depiction that any account should explain, I sketch an account that does this. The account understands depiction in terms of the experience to which it gives rise, and construes that experience as one of resemblance. The property in respect of which resemblance is experienced was identified by Thomas Reid, in his account of ‘visible figure’. I defend the account against (...) certain criticisms, and compare it to some of its main rivals, in particular the views offered by Goodman, Wollheim and Dominic Lopes. (shrink)

Can indistinguishable objects differ aesthetically? Manifestationism answers ‘no’ on the grounds that (i) aesthetically significant features of an object must show up in our experience of it; and (ii) a feature—aesthetic or not—figures in our experience only if we can discriminate its presence. Goodman’s response to Manifestationism has been much discussed, but little understood. I explain and reject it. I then explore an alternative. Doubles can differ aesthetically provided, first, it is possible to experience them differently; and, second, those (...) experiences reflect differences in the objects’ themselves. A range of objections to this position is considered, but all are found wanting. (shrink)
